Definitions

  • Such a lamp is known from EP-A-0 169 165.
  • the solution according to the invention enables the light failure of the lamp to be adjusted in a desired direction by the axial rotatability of the connecting profile, while at the same time and under all circumstances it is ensured that the live parts in the holding heads or at the outer ends of the lamp tube are protected against contact.
  • the arrangement of a connecting profile between the holding heads ensures great stability of the lamp when assembled, while the type of connection of the connecting profile with the holding heads ensures easy assembly and disassembly of the individual parts of the lamp.
  • the connecting profile is designed as an extruded profile, the parts of the ring web remaining there continuing after a recess for reaching behind it and also webs running in the longitudinal direction over the length of the connecting profile, since then a particularly simple manufacture is possible.
  • the connecting profile 3 or the holding heads 2 By rotating the connecting profile 3 or the holding heads 2 by 90 ° with respect to the position shown in FIG. 4, the ring webs 24, 25 are brought out of engagement with the annular groove 32 of the connecting profile 3, and the connecting profile can be perpendicular to the longitudinal and connecting axis of the Retaining heads 2a, 2b can be removed from these, since in this position the flattened surfaces of the retaining heads 2 are between the chamfers 31 of the profile body 30 of the connecting profile 3 and thus permit removal.
  • FIG. 8 The embodiment shown in perspective in FIG. 8 is a luminaire design, which corresponds in principle to the representation according to FIG. 1.
  • the elements that are not described in greater detail correspond to the elements of the exemplary embodiment described above, which are provided with a reference symbol reduced by 100.
  • the arrangement of these recesses which interrupt the ring web corresponds to the arrangement of parts 127, 128, 129, 129a of a ring web which are provided on the ends of the connecting profile 103 which receive the holding heads 102a, 102b.
  • the arrangement of the remaining areas of the ring web 124, 125, 124a, 125a, 126a on the holding heads 102, 102a also corresponds to the arrangement of recesses interrupting the ring web 127 to 129, 129a at the ends of the connecting profile 103, so that in the assembled state the light engages behind the parts of the ring web of the holding heads those of the connecting profile.
  • the arrangement of the parts of the ring web and the recesses is equidistant in the circumferential direction.
